 There are a few preparation steps required before a cross chain transfer, which need to be done only once for each chain. If these steps are already completed, you can skip this part.
 
-Let's say you want to transfer token **FOO** from chain **A** to chain **B**. Before you start, make sure you understand how cross chain transaction verification works. Any input containing `MerklePath` in the following steps means that cross chain verification is needed. Refer to the [cross chain verification documentation](crosschain-verification) for more details.

-Upon creating a new proposal for the side chain, the `ProposalCreated` event containing the proposal ID will be fired. A parliament organization, specified since the chain's launch, will approve this proposal within 24 hours (refer to the [Parliament contract documentation](../../../reference/smart-contract-api/parliament) for details). The proposer can release the side chain creation request with the proposal ID once it can be released.
